Must have a building inspection done , My builder charges $220.00 for a written report. then u know what has to be done to bring it up to scratch. Last IP we purchased the report showed the car port wasn't cleared by the council , so the vendors had to fix that up before the sale went ahead. Also I ask my electrician , plumber and the pest sprayer for reports. The electrician pick up the old wiring had to be replaced in another IP before purchase.
cheers
